Abstract
The invention is a portable external modular filtering and contamination removal system for a ship. A plurality of non-fixed position modular filter assemblies filter and remove macro-, micro- and nano-particle contaminates ship-side. The filter assemblies may be vessel-based or port based. A floating access and maintenance unit provides easy access to the filter assemblies. The filter assemblies move in cooperation with each other to spread the discharge over multiple units. A flow collecting and diverting apparatus seals against the ship to prevent discharge from running down the side of the ship with a directional discharge to divert discharge to waiting filter assemblies. The filter assemblies may provide their own buoyancy, obtain some buoyancy from vertical support lines from the deck of the ship or shift the buoyancy needs partially or wholly to the floating access and maintenance unit.

In this embodiment, smaller external
modular filtering systems 10 may be used because they do not need to provide all of the desired buoyancy or faster filtering can be accomplished because the externalmodular filtering system 10 can handle a greater load in a shorter period of time. In this embodiment the portable externalmodular filtering system 10 may easily be vessel-based rather than port based and a small boat may be used to access and maintain the filtering assembly eliminating the need for the modular dock sections. - Now referring to
FIG. 2 , another embodiment is where thefilter assemblies 20 are placed on the floating access andmaintenance unit 40 where the floatingunit 40 is secured to the ship and thefilter assemblies 20 move on theunit 40 or within the floatingunit 40 using an automatic or manual propulsion system such as a turntable. This embodiment shifts the variable buoyancy to the floating dock provider who may be port-based and have access to a wide variety of configurations offilter assemblies 20 and a wide variety of modular floating docks or small boats. - Another embodiment is of the filtering system is where
filter assemblies 20 are placed on the floating access andmaintenance unit 40 where the floatingunit 40 moves horizontally along the side of the ship using an automatic or manual propulsion system. - Another embodiment of the filtering system may also employ hydrocarbon absorbing materials in the areas where water exits from the filtering system to absorb oil and other hydrocarbons that may be present in the discharge. Another embodiment may also employ water sampling devices to collect samples of water at applicable stages of the water filtration.
- Now referring to
FIG. 3 andFIG. 4 , a flow diverting andcollection apparatus 50 for use with the externalmodular filtering system 10 comprises a sealingedge 52 to mechanically connect with the side of theship 12 to divert discharge 18 (FIG. 4 ) from exiting theport 16 of theship 12 and running down the side of theship 12 during discharge; a divertingmechanism 54 diverts discharge in one or more alternating directions away from theship 12 into the externalmodular filtering system 10; acollection mechanism 56 temporarily holds a volume of discharge before it exits to thefiltering assemblies 20 through anorifice 58. A release mechanism may release the flow from the collection mechanism. The flow diverting andcollection apparatus 50 may have the sealingedge 52 held in place at the side of theship 12 with magnets. - A method of using the external
modular filtering system 10 comprises the steps of: - A decision is made on whether to have the
filtering assembly 20 provide its own buoyancy or have the buoyancy provided by the floating access andmonitoring units 40; this decision is made depending on the availability of floatingunits 40 and the availability of buoyant vertical support frames 34; if the buoyancy is to be provided by thefiltering assembly 20, buoyantvertical frames 34 are used, otherwise other materials may be used; the phrase ‘buoyant vertical frame’ 34 should be assumed below where applicable; - Each layer of
filtering assembly 20 is assembled by attaching the appropriate multi-sidevertical frame 34 to the correspondinghorizontal platform 32 with mechanical connectors and attaching theappropriate filter material 22 usingmechanical connectors 28 on the top leaving enough slack so that thefilter material 22 can accommodate atemporary filter pool 36; - Additional layers (
vertical frame 34,horizontal platform 32,multiple filter materials 22, mechanical connectors 28) are used depending on the level of filtering desired (macro-particle, micro-particle or nano-particle); - An additional
horizontal platform 32 may be added on top of the top layer to serve as a shock absorber to dissipate the force of the discharge and to collect large pieces of debris; - Additional serial units are used depending on the speed of filtering desired;
- The portable
external filtering system 10 is placed below theexit port 16 of theship 12; - A flow diverting and
collection apparatus 50 is placed below theexit port 16 of theship 12 at a level high enough to divert the discharge appropriately; a surrounding net or waterproof shield may be employed in conjunction with the flow diverting and collection apparatus to prevent splashing discharge from contaminating ambient water; - Vertical support lines may be secured from the ship deck to the external filtering system to add buoyancy to the operation when needed;
- The
filtering assemblies 20 and/or floating access andmaintenance unit 40 can be secured to the ship during operation using magnets or other means or may be moved as appropriate during discharge to keep the load spread out to speed up the process; moving may be accomplished manually or automatically; - Discharge is commenced with visual monitoring and visual and audio communication used to communicate between the crew controlling the discharge and the crew for the floating access and
maintenance unit 40 where feedback between the crews can result in decreasing, increasing or ceasing discharge as required and changingfilter material 22 when and where required; - After the discharge is finished discharging and filtering, the
filter material 22 and the contaminants can be rolled up and put into plastic bags to be reported, tested, studied and/or destroyed as appropriate for the type and level of contaminant and the local regulations. - The above disclosure is sufficient to enable one of ordinary skill in the art to practice the invention, and provides the best mode of practicing the invention presently contemplated by the inventor. While there is provided herein a full and complete disclosure of the preferred embodiments of this invention, it is not desired to limit the invention to the exact construction, dimensional relationships, and operation shown and described. Various modifications, alternative constructions, changes and equivalents will readily occur to those skilled in the art and may be employed, as suitable, without departing from the true spirit and scope of the invention. Such changes might involve alternative materials, components, structural arrangements, sizes, shapes, forms, functions, operational features or the like.
